I've only checked the ones in the original post so far (takes me a bit to load is all ), but what I saw was gold!

That muskateer is my fave by far, it's a very well-done piece of artwork. I like the way you made the figs' sleeves look all fabric-like.

Love the white hand on the Orc's shield.
It's funny, I did the same thing for a minifig I made (Some Marvel character), by making the handprint on his belt look like a LEGO hand, and I did it just as you had. But within the past week I was debating whether I should have only drawn the main "U" shape, since the rest would truly be the fig's wrist or whatever.

Ok, I just rambled a lot about that, but really, I never thought about that when designing the decal. But it just recently hit me that it really didn't make sense when you think about it that way.

..For some reason though, it seems like it wouldn't be as easily recognized as a minifig hand that way, though.. Hmm..

Anywho,
keep on drawing! I've always been a big fan of LEGO related artwork, and this stuff is great!
